On 24 October your 0100 DR position is LAT 27°42' N, LONG 158°35' E. You are on course 085°T at a speed of 12 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0700 running fix.

Correct Answer: Option B — LAT 27°56.0'N, LONG 159°47.3'E

Celestial navigation running fixes require advancing lines of position along the DR track. Steaming on course 085°T at 12 knots for six hours from 0100 to 0700 translates the initial position to LAT 27°56.0'N, LONG 159°47.3'E.
